    Hi all,
    More progress.
    I have made brackets for the vacuum pump and alternator. The only concern I have is the belt contact on the alternator. I can run a second belt from the crank pulley to the alternator pulley if it becomes an issue.

    Here is the CAD(cardboard aided design) template I started with. The alloy round bar is for the spacers. And I used 6mm alloy flat bar.

    Sort of jumped the gun with photos. Here is the finished product. The adjuster is a sbc one I bought and cut all the crap off it.

    This spacer connects to the adjuster. I made it an interference fit which seems to have worked great.

    I also have the -12 welded to the rocker cover and a breather welded into the other for the vacuum pump. I will take some pics and post.
    We are looking at Dyno time in the next week or two. They havent finished installing the dyno yet.
    Cheers

    WOW.... what did you do to my oil pan? lol

    Nice addition. It's nice when you don't have the constraints of the stock frame and cross member to confine your creativity!

    Looking good!!

    Sorry about that Steve:( I know you put a lot of time and effort into it, and I put a lot of money into it:eek:
    What do you think of the windage Steve? should I have made some more holes in it around the large opening?

    Thanks for the comments guys. Getting very close now. Problem is I have been asked by one of my clients to work 12+hrs a day for the next 2-3 weeks:shock: Not much time for the motor
    Cheers

    Royden, with the sump that low and far away from the crank you'll be fine. Just keep the oil level (at least) one quart low on the dipstick to keep oil from residing in the front sump.
    I told mike that for the amount of work put into those steel conversion pans I could build a killer aluminum one that would be better all around. He was worried about running an aluminum pan on the street. I've done it for years. They are tougher than they look.

    Anyway.... the engine looks outstanding!!

    An aluminum pan sure would of looked good, but like you say Mike didn't want any problems with it cracking or splitting. Mike didn't want to build so much horsepower into the engine because he thought it was to much for the street :) and the car for that matter.
    I ended up sending him photos of the chassis that I built, to show him how strong this car will be to put his mind at ease. As it happened, we chose a smaller cam to make it drivable:shock: on the street.
    Thanks for your input Steve.
    Cheers

    Hi all,
    I received my fuel pump last week. Its a Product Engineering 310gph model. Just have to make a bracket for it now.

    It is so close to running on the dyno now. I have an issue with flexplate to starter clearance that I am trying to resolve. Its a JW flexplate and a RobbMc mini starter.
    Anyway, I have had some fittings added to the rocker covers for the vaccum pump. The vacuum pump will also be plumbed to my brake booster resivoir tank to help with the brake pedal.

    I also made an aluminum bracket for the race coil.

    I thought I would throw these in here too. This is my diff setup.

    Royden,
    Great build. I ran a vacuum pump on my last race motor, and picked up quite a bit of horsepower. I noticed on the picture of the vacuum pump lines/fittings that you have a standard breather on the other valve cover. Maybe this is not a breather, but if it is, this will serve as a path straight to outside atmosphere and not let the pump create any vacuum in the crankcase. You might want to consider a regulator at that location so you can adjust the amount of vacuum pulled.
    That piece is one beautiful motor!

    Hi Jeff
    The tube that the filter is mounted to has a baffle in it which I can close off. I bought an aeromotive adj vacuum reg that I will mount off the vacuum pump with a small gauge on it so I can set the vacuum properly.
    If at any stage I wish to not use the vacuum pump I have a breather.
    Cheers

    Hi all,
    I am struggling to find some #25 Holley jets that I need for my oil restrictors.
    Hopefully a few of the TA455 owners see this and can advise me on what they are running. Jim W has used #25 in the E85 race motor he documented in this forum.
    Anything please.
    Cheers

    Hi Devon,
    Yeah I already bought those from Summit thinking they are what I need. But I was wrong. These jets are probably a third the size of normal holley jets unfortunately. The ones I need have the prefix '122' not '142'.
    Cheers

    We are going to braise up some jets and drill them at 0.025"
    If they don't give me the oil that I need at the top then I can drill them a bit more
    Cheers

    Mike,
    This is a bit of a plug for you. All the way from Australia.

    Again

    I have an open day coming up for a friend of mine who is a coach builder/metal magician and I will be starting the motor for the first time then, hopefully. No load, just starting it for the first time. Then I will remove it from the car and put it on the dyno. It means I can delay $1000.00 + a day of charging for work.
    I will start posting some pics of the car even though not Buick, soon to show the progress and what this motor is going to drive!
    Cheers

    Great progress, that all looks awesome! I hope the friday "runs" are problem free....I'll bet Friday can't get here soon enough! I may have some "exciting" updates regarding my Tomahawk Build this Friday too.

    Royden,

    The pictures look great but at this point we really need video with sound!!! :grin:

    It will be ready to run this afternoon (doing nightshift at the moment) but everyone is coming around on Friday to see it. Ive been waiting since 2009, so whats another couple of days :rolleyes:
    Might be a great day for the Tomahawk Gary?

    There will be plenty of video as I have stirred a lot of interest here in Australia. I think most people here in Australia dont get that its the only alloy BBBuick outside the US and probably the most powerful too:beer
    Cheers

    I'm kind of curious why Mike T recommended 20/50 oil. Did he tell you why he suggested thicker oil?
